Why don't some countries show their entry and exit records? What happened?

Due to system delay, some countries do not display entry and exit records. Incoming and outgoing records cannot be found, which may be due to system delay. Just wait 1-2 days. Entry-exit records can be inquired through WeChat applet "Immigration Bureau", Alipay applet "Immigration Bureau", any entry-exit administration department in China or port border inspection authorities.
